Specification of Letters Patent.

Patented Mar. 10, 1914.

Serial No. 609,795.

To all whom it may concern:

Be it known that I, JOSEPH BECK, a citizen of the United States, residing at Two Harbors, in the county of Lake and State of lvlinnesota, have invented certain new and useful Improvements in Furnace-Grates, of which the following is a specification, reference being had therein to the accompanying drawing.

My invention relates to improvements in furnace grates, and pertains more particularly to grates used in corrugated furnaces.

The object of my invention is to provide a grate for a furnace of this character in which a larger grate area is obtained without altering the dimensions of the furnace and thus increasing the etliciency of the boiler.

Another object of my invention is to provide a more simple, cheap and effective grate having certain details of structure hereinafter set forth in the specification.

In the accol'npanying drawings Figure 1 is a horizontal sectional view, partly broken away, of a corrugated furnace equipped with my improved grate bar. Fig. 2 is an enlarged side elevation of a portion of a grate showing a modified form. Fig. 3 is an en largcd side elevation of Fig. 2, showing the furnace in section.

Referring now to the drawings, 1 represents the walls of a corrugated furnace, such as are in common use, and 2 represents the grate bars that are usually used in simple furnaces of this ..character. The Slt'lQlJRIS 3 of my improved grate are very similar to the intermediate bars 2, except that they have removably secured thereto the laterally extending stub-bars 4:, extending within the convex corrugations of the furnace walls 1, thus providing much more grate surface without increasing the size of the furnace or boiler, will be readily seen. The side-bars adjacent their lower ends are provided with laterally extending projections 6, upon which the removable plate 5 rests, and said plate resting flat against the side of the side-bars 3 and secured thereon in any desired manner. The lateral stubs 4*.

in this form are formed integral with the plate 5, and extend out and engage the sidewalls 1 of the boiler. The lower extremity of the plate 5 is provided with a suitable foot 7 which rests upon the upper face of the laterally extending projections G, whereby the weight of the plate 5 and its load is supported by the projections (3. The upper edge of the plate 5 is beveled or slanting as indicated at 9 to prevent ashes and the like resting upon the upper edge. It is evident that this device is applicable to various forms of either stationary or shaking grates.

l aving thus described my invention, what I claim and desire to secure by Letters Patout is:

l. A grate for corrugated furnaces, the side bars of the grate having laterally extending projections at their lower faces spaced apart, plates having a beveled upper edge and laterally extending spaced grate fingers adapted to project within corrugations of the furnace, said plates resting against the side bars and having tapering lower ends terminating in reduced laterally extending projections resting upon the projections of the side bars and extending beyond the same and means for securing said plates to the side bars.

2. A grate for corrugated furnaces, the side bars of the grate having laterally ex tending projections at their lower sides spaced apart and gradually tapering in width, plates having laterally extendin spaced grate fingers adapted to extend within the corrugations of the furnace, said plates resting against the side bars and having tapering lower ends terminating in lateral projections gradually tapering in width and resting upon the projections of the side bars, and means for securing the plates to the side bars.
